The seal bar consists of the following components
Seal wires: the sealing wires are heated for a
certain period of time so that the open side of the
vacuum bag will melt together during the sealing
Cutting wire (optional): a cutting wire is heated in
such a way that the foil of the bag partially melts
so that the top flap of the vacuum bag can be
torn off easily
Teflon-tape: sealing and cutting wires are coated
with Teflon tape to prevent the bag to stick to the
seal bar
Refer to the indicated section for detailed information
on maintenance
Opposite to each seal bar a silicone holder is
mounted, which provides counter-pressure on the
cylinders / seal bag
The seal bars are pressed on the vacuum bag by
using cylinders or seal bags
By connecting the outside atmospheric pressure to
the inlet of the cylinders, they will press the seal bar
on the bag
